Detailed Website Analysis

The basic overview not enough? Let's dive deeper.

khanacademy.org Data In-Depth

A website is not just Quantcast ranks and meta information. There is a whole lot more to it. Let's give it a proper look now, shall we?

khanacademy.org Safety Information

Website safety is a key factor that should not be underestimated. After all, our computers and personal information stored on them are not as secure as one might think - the recent flaws found in microprocessors only confirm this. There is more than one source for finding out if a website is safe to visit or not, some more dependable than others. In this section we'll try to cover all the bases, if at all possible.

• Craeted by Symantec - a California based cyber security experts - Norton is among the most recognized security solutions you'll come across. Because of that, we put a lot of faith in their findings. Symantec assessed khanacademy.org with its Norton software and found it to be no_data. The experts did not identify any annoyance factors on the website. Symantec could not find any computer threats. And to finish this report on a bright note, no identity threats were found!
• We will be honest, whether to include WoT (or Web of Trust) assessment in this report or not has been a lengthy debate. Unlike the imperious Symantec (the company behind cyber security software Norton), WoT is less than trustworthy, as ironic as that may sound. A whole bunch of their negative reports are known to be completely wrong and even damaged the reputation of a few websites. What's arguably much worse, WoT actually sold/distributed personal user data to third parties without the former's consent. Still... just in case they are right, even if one time out of a hundred, we figured it was worth including their assessments. Just keep the context in mind and don't trust them blindly. Overall, WoT has given khanacademy.org a Trustworthiness rating of 95 out of 10. As far as Child Safety rating is concerned, it's been rated at 95 out of 100. Keep in mind Web of Trust is not exactly trustworthy, and it's hard to imagine such a reputation dissolving anytime soon.

khanacademy.org Traffic Statistics

The following statistics are provided only as an approximation. We can't guarantee the numbers are absolutely correct, but we do believe they are very much within the ballpark and, as such, can give a pretty good idea about the popularity of this website.
Let's start with some telling numbers and then break it all down.

Page speed overview

• It takes around 1.4439 seconds for the homepage to fully load. This is a very good result, as search engines prioritize websites that are quick to load.
• It's worth to note the HTML of the page is around 142.9 kilobytes in size. A good result that should not impact load speed in any negative way.
• Judging by tags, the homepage contains at least 14 images. A great amount! Not too many, at least. Images should not impact page load speed negatively.
• Our database tells us around 64 server requests are made before the homepage is loaded completely. Wow, that's a lot. Certainly, so many server requests contribute to slower page load times.

Alexa rank up close and personal

Alexa, perhaps the oldest ranking system of its sort, bases it's website rating on approximated number of visitors of a specific page. In other words, the more visitors, the higher the global and local ranks. As of recently, Alexa has well over four million websites ranked. Having said all that, Alexa rank should be taken with a grain of salt. Or a massive bucketload. In other words, we think it to be greatly overrated, as it never takes into account how popular a website is within its niche.

• Alexa claims khanacademy.org takes up 703 place globally, among all the indexed websites. We updated this information on 2018-01-29.
• Compare that to the best rank this website has taken 2017-10-25, which is 497.
• The delta of this rank over the last three months is around -171.
• As far as we know, the worst position for khanacademy.org was 4,739 (on 2013-12-10).
• The average Alexa rank for khanacademy.org is 1,635 at this time.
• It's worth to mention that in United States, khanacademy.org is in 244 place.

QUANTCAST rating in detail

QUANTCAST is very similar to Alexa, though perhaps enjoys an overall better user opinion even if, by comparison, the data processing company's rank index is smaller. The main interest of QUANTCAST is real-time audience analysis, so again the rank is based on traffic. QUANTCAST gathers this data mainly for advertising purposes of other companies. We know that, so far, QUANTCAST has ranked 4,545,871 websites, give or take a few. With all of this said, Quantcast rank is not really any more useful than that of Alexa and most similar ranking systems. Few of them, if any, take context into account and rate websites purely on traffic numbers (guesstimated, in so many cases). It's by far not the most accurate representation of a website's worth.

• As reported by Quantcast, the website takes up 5,281 place globally. This rating was last checked on 2015-02-05.
• The best Quantcast rank of 2,898 was achieved on 2014-10-21.
• As far as we know, the worst position for khanacademy.org was 9,256 (on 2014-06-19).

Host Server In-Depth

What is a server? It's basically a physical storage device (one that, sometimes, makes up several virtual servers for the cheaper shared hosting) that holds all the files and databases associated with a specific website or websites. Obviously, it's a touch more complicated than that (servers also have processors), but the essence is quite simple - your browser contacts the server, which then sends all the neccessary information and files to your computer. Each physical server has a unique IP address assigned to it, too, for easy recognition.

• The current IP address for this website's server is 72.14.249.132.
• Server seems to be online.
